Answer:
7
Step-by-step explanation:
Let x be the required natural number.
According to question
x + 1/x = 50/7
7x^(2) + 7 = 50x
7x^(2) -50x + 7 = 0
7x^(2) - 49x - x + 7 = 0
7x ( x -7 ) - ( x - 7 ) = 0
( x - 7) ( 7x - 1) = 0
x = 7 or 1/7
Since, x is natural number.
Therefore, x cannot be equal to 1/7.
Hence, 7 is the required number.
